Am I making the most of my graphics card on my Dell XPS 15 9570?

Yashy used Ask the Experts™
hi guys

I have a Dell XPS 15 9570, with an Nvidia Geforce GTX 1050Ti (4GB) graphics card. It also has an Intel UHD Graphics 630.

The question I have is, am I making the most out out of my display for performance? When I go in to the actual Nvidia control panel, I have attached a screenshot of what it shows. It hasn't selected the Geforce, but instead the Intel UHD?

NOTE:  If dbrunton's comment below is correct, ignore this posting entirely.

If the Nvidia can drive everything you intend to use (both the built-in and any external displays), then bring up Device Management and permanently disable the Intel.  This will solve the issue at a possible cost of creating a short-term spate of new issues as things which expected to use the Intel find it's not there any more.

Do not confuse disabling a device within Windows with disabling in the BIOS.  Disabling it within Windows means Windows will not use the device but the device is still present and functioning normally.  Disabling it within the BIOS means it will not be present at all.

This is not an uncommon problem as when two similar devices are present, Windows reliably picks the one you don't want to use.  E.g., this system with both built-in analog sound and an HDMI sound interface on the video card.  The HDMI sound interface must be permanently disabled, otherwise Windows keeps reverting to the HDMI sound.

Some of the following comments may not necessarily apply to your system.  Read carefully.

Now my understanding from using Google is that everything goes through the Intel GPU and the Nvidia is a co-processor.  See  for more information.

See  on making applications use the Nvidia GPU

Your graphic is showing the PhysX engine, a product of Nvidia.  It usually comes with Nvidia cards and can use either a Nvidia graphics card or the CPU to help accelerate games.  (It may be used in other applications but I'm not aware of those).  Usually you let the PhysX auto-select which way to (as your graphic shows).

Well done, dbrunton.  This is a configuration I have never seen before.

Yes, it is new to me as well.

I actually thought you'd switch which GPU you'd use on the laptop (perhaps as another graphics connector) but a pass through system is definitely something new.


Thank you both for your input. Dbrunton, that is a very helpful link. So annoyed at Dell. It's like I have been misold something entirely.
